Description

一种显示面板和显示装置 【技术领域】
本申请涉及显示技术领域，更具体的说，涉及一种显示面板和显示装置。
【背景技术】
显示器具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的显示器大部分为背光型显示器，其包括显示装置及背光模组(backlight module)。显示装置的工作原理是在两片平行的基板当中放置液晶分子，并在两片基板上施加驱动电压来控制液晶分子的旋转方向，以将背光模组的光线折射出来产生画面。
其中，薄膜晶体管显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)由于具有低的功耗、优异的画面品质以及较高的生产良率等性能，目前已经逐渐占据了显示领域的主导地位。同样，薄膜晶体管显示器包含显示装置和背光模组，显示装置包括彩膜基板(Color Filter Substrate，CF Substrate，也称彩色滤光片基板)和薄膜晶体管阵列基板(Thin Film Transistor Substrate，TFT Substrate)，上述基板的相对内侧存在透明电极。两片基板之间夹一层液晶分子(Liquid Crystal，LC)。显示装置是通过电场对液晶分子取向的控制，改变光的偏振状态，并藉由偏光板实现光路的穿透与阻挡，实现显示的目的。
另有一种OLED显示器，采用有机发光二极管(Organic Light-Emitting Diode,UIV OLED)进行自发光显示。与液晶显示(Liquid Crystal Display,LCD)是不同类型的发光原理。OLED显示技术具有自发光、广视角、几乎无穷高的对比度、较低耗电、极高反应速度等优点。
现有的显示面板都需要采用胶水进行基板之间的固定，但现有的胶水涂布和固化需要昂贵的设备投入，且生产时间较长。
【发明内容】
本申请所要解决的技术问题是提供一种降低生产材料成本，提升生产效率的显示面板。
本申请的目的是通过以下技术方案来实现的：
一种显示面板，包括，
第一基板，
第二基板，与第一基板相向设置；
胶框，形成于第一基板和第二基板之间；
所述胶框采用自挥发固化或热固化胶粘剂制成。
进一步的，所述第一基板上设置有配向层；所述胶框同时涂布在配向层和第一基板上。第一基板一般是玻璃材质，玻璃材质不会吸收水汽，粘贴更稳定；而配向层为有机材质，与配向层材质相近，附着力强，因此，胶框同时粘贴在第一基板和配向层上，可以兼顾粘贴强度和稳定性。
进一步的，所述第一基板上设置有配向层；所述胶框仅涂布在第一基板上；所述配向层设置在所述胶框的内侧位置。第一基板一般是玻璃材质，玻璃材质不会吸收水汽，粘贴更稳定，在显示面板长期使用过程不易脱落，有利于提高产品的稳定性。
进一步的，所述第一基板在所述胶框对应位置设有第一凹槽。由于第一凹槽的存在，胶粘剂在涂布的时候不易流动，可以稳定附着在第一凹槽附近，在贴合固化的时候，胶粘剂会受到挤压，也不容易扩散到显示面板的显示区域内，污染液晶分子，有利于提高显示品质。
进一步的，所述第一基板上设置有配向层；所述胶框仅涂布在所述配向层上。配向层为有机材质，与配向层材质相近，附着力强，有利于提高粘贴强度。
进一步的，所述第一基板上设置有配向层；所述第一基板在所述胶框对应位置设有第二凹槽；所述配向层在第二凹槽对应位置形成第三凹槽。由于第三凹槽的存在，胶粘剂在涂布的时候不易流动，可以稳定附着在第三凹槽附近，在贴合固化的时候，胶粘剂会受到挤压，也不容易扩散到显示面板的显示区域 内，污染液晶分子，有利于提高显示品质。
进一步的，所述胶粘剂包括丙烯酸酯化合物。丙烯酸酯化具有高极性和完全饱和性。从而使其具有优越的耐矿物油和耐高温氧化性能。其耐油性仅次于氟胶，而与一般中高丙烯晴含量的丁腈橡胶相似。而耐热性介于通用橡胶和硅、氟橡胶之间，比丁腈橡胶使用温度高出30～60℃，最高使用温度180℃，断续和短时间使用可达200℃，在150℃热空气老化数年性能无明显变化。此外，最重要的是其对含有硫、氯、磷等极压剂的极压型润滑油十分稳定，使用温度可达150℃，间断使用温度可更高些。而带有双键的丁腈橡胶在含有极压剂的油中，当温度超过110℃时，即发生显著硬化与变脆。丙烯酸酯橡胶还具有优良的抗臭氧性、气密性、耐屈挠和耐裂口增长性，以及抗紫外线变色性等。因此，利用丙烯酸酯作为本申请的胶粘剂，可以利用热固化的方式进行固化，热固化设备简单，成本低廉，且固化时间短，有利于提高生产效率。
进一步的，所述胶粘剂包括铝硅氧烷、两末端硅烷醇型硅油和硅氧烷烷氧基低聚物的化合物。通过铝硅氧烷、两末端硅烷醇型硅油和硅氧烷烷氧基低聚物之间产生缩聚反应，得到具有透明性、多交联数、高的交联密度、和大的键能的化合物，不仅可以呈现出优异的透光率和耐热性，而且呈现出优异的抗拉弹性模量。在分解有机物质的紫外线区域不具有吸收，不易受到因光所导致的劣化，所以密封时呈现出优异的亮度保持率。因此，该胶粘剂可以作为良好的热固化黏合材料，热固化设备简单，成本低廉，且固化时间短，有利于提高生产效率。
进一步的，所述胶粘剂包括α－氰基丙烯酸乙酯化合物。物化性质:无色透明、低粘度、不可燃性液体，单一成分、无溶剂，稍有刺激味、易挥发、挥发气具弱摧泪性。遇潮湿水气即被催化，迅速合固化粘着。固化后无毒。接触空气中微量水汽，即被催化迅速聚合固化粘着之特性，因此可以快速固化。因此，利用α－氰基丙烯酸乙酯作为本申请的胶粘剂，可以利用自挥发的方式进行固化，无须额外的固化设备投资，成本低廉，且固化时间短，有利于提高生产效 率。
根据本申请的另一个方面，本申请还公开了一种显示装置，该显示装置包括本申请所述的显示面板。
本申请采用自挥发固化或热固化胶粘剂作为胶框材料，热固化胶粘剂需要的温控设备较为低廉，且固化速度可控，相比复杂的紫外线固化设备及涂布设备，具有成本优势，且生产效率更高。而自挥发的胶粘剂完全不需要固化设备，成本进一步降低。

可选的，采用丙烯酸酯化合物作为热固化胶粘剂。丙烯酸酯化具有高极性和完全饱和性。从而使其具有优越的耐矿物油和耐高温氧化性能。其耐油性仅次于氟胶，而与一般中高丙烯晴含量的丁腈橡胶相似。而耐热性介于通用橡胶和硅、氟橡胶之间，比丁腈橡胶使用温度高出30～60℃，最高使用温度180℃，断续和短时间使用可达200℃，在150℃热空气老化数年性能无明显变化。此外，最重要的是其对含有硫、氯、磷等极压剂的极压型润滑油十分稳定，使用温度可达150℃，间断使用温度可更高些。而带有双键的丁腈橡胶在含有极压剂的油中，当温度超过110℃时，即发生显著硬化与变脆。丙烯酸酯橡胶还具有优良的抗臭氧性、气密性、耐屈挠和耐裂口增长性，以及抗紫外线变色性等。因此， 利用丙烯酸酯作为本申请的胶粘剂，可以利用热固化的方式进行固化，热固化设备简单，成本低廉，且固化时间短，有利于提高生产效率。
可选的，采用铝硅氧烷、两末端硅烷醇型硅油和硅氧烷烷氧基低聚物的化合物作为热固化胶粘剂。通过铝硅氧烷、两末端硅烷醇型硅油和硅氧烷烷氧基低聚物之间产生缩聚反应，得到具有透明性、多交联数、高的交联密度、和大的键能的化合物，不仅可以呈现出优异的透光率和耐热性，而且呈现出优异的抗拉弹性模量。在分解有机物质的紫外线区域不具有吸收，不易受到因光所导致的劣化，所以密封时呈现出优异的亮度保持率。因此，该胶粘剂可以作为良好的热固化黏合材料，热固化设备简单，成本低廉，且固化时间短，有利于提高生产效率。
可选的，采用α－氰基丙烯酸乙酯化合物作为自挥发固化的胶粘剂。α－氰基丙烯酸乙酯无色透明、低粘度、不可燃性液体，单一成分、无溶剂，稍有刺激味、易挥发、挥发气具弱摧泪性。遇潮湿水气即被催化，迅速合固化粘着。固化后无毒。接触空气中微量水汽，即被催化迅速聚合固化粘着之特性，因此可以快速固化。因此，利用α－氰基丙烯酸乙酯作为本申请的胶粘剂，可以利用自挥发的方式进行固化，无须额外的固化设备投资，成本低廉，且固化时间短，有利于提高生产效率。
